About Main Wall:

Thanks to John O'Brien... "The main wall is under vertical by 10–20 degrees. The columns run a little off plumb so climbs sometimes have a tendency to cross a few columns along the way. Most of the columns are jointed too tightly to allow even the smallest protection so bolts have become standard, however there are a few trad climbs. A band of overhangs or overlaps exist across the middle of the highest part of the main wall and also lower down, providing difficulties and interest."
